Vega’s C-

6124

This audio level will be inserted to an Automatic Level Control that will not allow audio to rise above
770mVrms. Setting TP21 for 600mVrms allows a good amount of audio deviation before the voice is
compressed (subjectively determined).

8.3 Other Adjustments

8.3.1 VU meter

RV10 on the UIM Analog board allows the setting of the sensitivity for the VU meter.

8.3.2 LCD Contrast

R38 on the UIM Digital board allows adjustment of the contrast on the LCD touchscreen.

8.3.3 Unselect Mute Level

The level that the Unselect audio will be at the time when it is muted is set by RV16.
